Title:
SECURITY PATTERN PRODUCING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/239138
Kind Code:
A1
Abstract:
The present invention provides a security pattern producing system, comprising: a printing substrate having an inducible ink coating printed on its surface, as well as at least one set of imaging photo-magnetic field and a set of curing photo-magnetic field for forming a variable security pattern on the surface of the printing substrate. The printing substrate is transported and sequentially passes through the photo-magnetic field and the curing photo-magnetic field. A imaging photo-magnetic field system comprises a optical field and a magnetic field, which are respectively arranged above and below the printing substrate. The magnetic fields is configured to induce the inducible ink coating of the printing substrate to form a magnetic field pattern, and the optical field is configured to use a transparent film as a pattern carrier to cure the part of the ink coating, which is induced by the magnetic field, corresponding to the pattern. The curing photo-magnetic field comprises a curing light source and a curing magnetic field. The curing magnetic field can re-induce the part of the ink coating that is not irradiated by the optical field, and the curing light source is configured to cure the re-induced ink coating. The pattern produced by the present invention has higher anti-counterfeiting degree.
